Michele Bachmann acknowledged House Speaker John Boehner’s debt-limit plan may pass, even without her vote — though she’s confident that the country won’t default even without a deal.

“I want to state unequivocally for the world, as well as for the markets, as well as for the American people: I have no doubt that we will not lose the full faith and credit of the United States,” Bachmann said Thursday. “I have no doubt that there will be a final resolve.”

Speaking and taking questions at the National Press Club, the Minnesota congresswoman and GOP presidential candidate gave a debt- and spending-focused stump speech and parried inquiries about her husband’s clinic and her federally backed mortgage.

Bachmann said that no compromise will get her to cast her vote for the Boehner plan.

“I will not be casting my vote for that bill. … I cannot. I am committed to not raising the debt ceiling,” Bachmann said.

But she laid the blame for the situation squarely on President Barack Obama.

“My colleagues may give the speaker that vote today. But despite John Boehner’s best efforts, absolute faithful efforts, to try and put a plan on the table, the problem goes back again to the president and his failure of leadership.”

Bachmann waved a copy of a January letter from Treasury Secretary Timothy Geithner to Senate Majority Leader Harry Reid that said the debt limit needed to be raised by mid-May at the latest, offering it as proof that the administration has been dishonest and has procrastinated in dealing with the issue.

Bachmann called on the president to support the bill she’s cosponsored to have the government continue to pay interest on the debt and military salaries with incoming revenues if the debt ceiling isn’t raised.

Bachmann addressed several questions about the controversies that have beset her campaign since her launch last month, including whether her husband Marcus’s Christian counseling clinic practices a discredited form of therapy that seeks to make gay people straight.

Asked about the clinic, which she co-owns and frequently cites as a small-business credential on the campaign trail, Bachmann didn’t answer whether she supports so-called reparative therapy and took a protective stance toward her personal life.

“I’m extremely proud of my husband. I have tremendous respect and admiration for him,” Bachmann said as he beamed at her from his seat on the dais — she noted that the couple will celebrate 33 years of marriage in September.

“But I am running for the presidency of the United States. My husband is not running for the presidency. Neither are my children, neither is our business, neither is our foster children,” she said.

Pressed as to whether her background doesn’t deserve scrutiny as she runs for the White House, Bachmann said with a broad smile, “I am running for the presidency of the United States, and I have no doubt that every jot and tittle of my life will be fully looked at and inspected prior to November of 2012.”

Bachmann also was asked about a report that she apparently purchased her home with a government-backed loan despite her vociferous criticism of the loan programs, Fannie Mae and Freddie Mac.

She didn’t deny the report, but added that government should leave the financial business to the private sector.

“This is the problem. It is almost impossible to buy a home in this country today without the federal government being involved,” she said.

Asked about whether the media has been fair to her, Bachmann didn’t take the bait, saying she “knew it would be tough” when she decided to run and that growing up with three brothers prepared her for the rough-and-tumble of politics.

For news, she said she goes first to outlets she considers liberal to see what they’re saying. She cited MSNBC, The Huffington Post and The Daily Beast.

Bachmann was the only House Republican absent for Thursday afternoon’s vote to proceed to the debt ceiling vote as she made her way back from the speech.
